The value of 43-3× (4×6+12/3 ×6-4×5) +4?
360 ÷ 9 + 15 % of 200 + ? * 10 = 45 * √25
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 ×9.05 =?
68% of 450 – 1008 ÷ 14 + 516 ÷ 43 =?
26% of 950 + 50/3% of 7962 = ?
1(1/2)+ 11(1/3) + 111(1/2) + 1111(1/3) + 11111(1/2) = ?
[(7/8 of 640 - 60% of 300) × (√225 ÷ 5)] ÷ (1/4 of 800) = ?
2(3/4) of 2880 + 54% of 7520 - ? = 302
